What does it mean when an object is said to be at rest?
- The object has zero velocity relative to some reference point. (correct)
- The object is in a state of constant acceleration.
- The object is moving at a velocity of 65 MPH.
- The object is not affected by any external forces.
Which statement about acceleration is true?
Which statement about acceleration is true?
- Acceleration has no effect on an object's state of motion.
- Acceleration involves a change in velocity. (correct)
- Negative acceleration results in the velocity remaining constant.
- Positive acceleration occurs when an object decreases its velocity.
